SPECIFICATION forming part of Letters Patent No. 492,177, dated February21, 1893.

Application filed November 21, 1892- Serial No. 452,700. (No specimens.)

To all whom it may concern:

Be it known that I, ADRIAN WOLFE, of Waterbury, in the county of NewHaven and State of Connecticut, have invented a new Improvement inMethods of Making Metal Mounts for Brushes, Hand-Mirrors, &c.; and I dohereby declare the following, when taken in connection with accompanyingdrawings and the letters of reference marked thereon, to be a full,clear, and exact description of the same, and which said drawingsconstitute part of this specification, and represent, in-

Figure 1, a view showing the blank or shell in the first stage of itsdevelopment. Fig. 2, a view showing the blank in the second stage of itsdevelopment, its closed end having been operated upon to partiallydevelop a handle. Fig. 3, a -view showing the blank or shell after thehandle has been developed. Fig. 4, a view showing the blank after it hashad an opening formed in it and been slit preparatory to the developmentof its open end. Fig. 5, a view showing the open end of the blank openedout and flattened, and the handle flattened. Fig. 6, a view showing theflattened open end of the shell trimmed into oval form. Fig. 7, a viewcomprising plan and edge views of the mount after the edge of its ovalouter end has been drawn up to form a rim or flange, and the metalwithin the same has been struck up into concavo-convex form. Fig. 8, aviewcomprisingplan edgeviewsand of my improved mount, furnished withabrush.

Myinvention relates to an improved method of making metal mounts forbrushes, handmirrors, and kindred articles, the object of the inventionbeing to produce at a comparatively low cost for manufacture, a seamlesssheetmetal article, pleasing and convenient in form, and by reason ofits seamlessness, capable of receiving a high and enduring finish.

\Vith these ends in view, my invention consists in first forming atubular sheet-metal shell or blank, closed at one end, then reducing theclosed end of the said shell, and developingit to form a handle, thenforming a centralized opening of transverse extension, in the shell atthe inner end of the handle, and slitting the shell from the center ofthe said opening outward, to its outer end, then opening out andflattening the said end of the shell,

a long tubular blank or shell A, from sheet- 63 metal, the said blankbeing closed at one end, uniform in diameter in its main portion, and ofconsiderable length as compared with its diameter, which is considerablyless than the width of the outer end or main portion of 65 the mountwhich it is designed to produce.

'In the drawing of this blank I may employ aluminum, brass, or any othersuitable metal or alloy. The blank may be either round, or

oval in cross section, its shape and size depending upon the characterand use of the mount to be produced.- Having secured such a blank, Ireduce its closed end by stripping, drawing or spinning, or someequivalentprocess, to form the partially developed handle B, shown byFig. 2 of the drawings, the diameter ot' the said partially developedhandle B, corresponding to the largest diameter of the completelydeveloped handle C, shown by Fig.

3 of the drawings, and produced by spinning,

or otherwise operating upon the partially developed handle 13. The shellis now cut away at a point just in advance of the inner end of thehandle, to form an irregular-oval opening D, the major axis of whichdoes not fall much short of the diameter of the shell which is slit openas at E, from the center of the said opening D, to its outer end. It isnot necessary that the opening described as being cut in the shell, havethe irregular oval form of the open- 0 ing D, but it should be oftransverse extension with respect to the length of the shell, and if theouter end of the mount is to be oval or curved when developed, the inneredge of the opening should be curved. When so 5 prepared by cutting, theouter end of the shell is opened out and flattened, as shown by F, inFig. 5 of the drawings. If new it is desired that the handle of theshell shall be flattened, it is filled with tallow, resin, or someequivalent material, to prevent it from caving in, and flattened to therequired form between suitable dies. This might be done before thedevelopment of the outer end of the shell is begun, but it will be foundmore convenient to do it, if at all, after the shell has been cut andopened out, which makes the interior of the handle more convenient ofaccess than it is before the shell is so cut and opened. The flattenedouter end F, of the shell is now trimmed into oval form, as shown by G,in Fig. 6 of the drawings. After this, the edge of the said oval isdrawn up at a right angle thereto, to form the rim or flange 11, shownby Fig. 7 of the drawings, and the metal within the rim is struck orshaped into concavo-convex form, as at I, in order to increase thecapacity of this end of the mount, and to make its exterior conformationcorrespond in its lines to the lines of the handle. After the brush J,has been set within the said rim, the edge thereof is turned inward overthe backing of the said brush, as at K, in Fig. 8 of the drawings. Ifdesired, the brush J, may be replaced by an oval glass, which would beheld in place in the same way by turning the edge of the rim orflangeinward over its edge, but in such use of the mount its outer end wouldprobably not be struck into concavoconvex form.

The mount produced in following my improved method, as thus described,is seamless, and is therefore particularly well adapted for receiving ahigh finish, for seams, in an article of this character, as is wellknown, interfere 1. A method of making sheet-metal mounts for brushes,hand-mirrors and kindred articles, consisting in first forming a tubularsheet-metal shell closed at one end, then reducing the closed end of theshell and developing it to form a handle, then forming an opening in theshell at the inner end of the handle, and slitting the shell from thecenter of the said opening to its outer end, then opening out andflattening the said outer end of the shell, and then developing the saidflattened end of the shell to adapt it to receive a brush or otherarticle, substantially as set forth.

2. A method of making sheet-metal mounts for brushes, hand-mirrors andkindred articles, consisting in first forming a tubular sheet-metalshell closed .at one end, then reducing the closed end of the shell anddeveloping it to form a handle, then forming an opening in the shell atthe inner end of the handle, and slitting the shell from the center ofthe opening to its outer end,then opening out and flattening the saidouter end of the shell, then trimming said flattened end of the shellinto oval form, then drawing up the edge of the said oval flattenedportion to form a rim or flange within which the brush or other objectis placed, substantially as set forth.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
